About the role
We're hiring a Staff Full-Stack Software Engineer (.NET & Azure) to join a fast-growing treasury platform giving businesses from SMEs to Fortune 500s real-time control over their liquidity, across traditional and digital assets. If you've spent 8+ years deep in C#/.NET Core, Azure, and Angular/TypeScript, and you're the person who doesn't just ship features but pushes back when there's a better way to build something — we want to talk to you.
What you'll be doing:
- Owning full-stack delivery (front-end, server-side, database) on a cloud-native Azure platform
- Setting technical direction and mentoring engineers around you
- Leading modernization of complex financial systems, not just maintaining them
- Working in a you-build-it-you-run-it culture with real ownership, not just tickets
What we're looking for:
- 8-10+ years hands-on with C#, ASP.NET Core, SQL ServerStrong Azure Services + Azure DevOps CI/CD experience
- Angular/TypeScript, TDD/BDD practice
- Financial services or capital markets experience a strong plus
- A track record of staying with teams and seeing hard problems through to closure — not a string of six-month hops
- Why apply through us:
- Fast-moving process — no lengthy interview loop, we manage the vetting upfront
- We back candidates who challenge the status quo, not just ones who tick boxes
Before you apply
Applying takes about a minute. These four things decide how fast it moves after that.
Your profile is current
It's what we read first. Occupations, seniority and locations matter more than a long history.
Two examples you can talk through
Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.
A number in mind
What you're on now and what would make you move. We negotiate better when we know both.
Your notice period
Employers plan around it, and it's the question that stalls offers most often.
Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
